350x 400ex ignition parts ?

[trikerider2oo7]

i was looking at some 400ex stuff on ebay and thought the plug on the cdi looked like the one on a 350x. will the cdi and coil from a 400ex work on a 350x? thanks

not sure but i believe these two engines are very similar i'm looking into putting a 400ex engine on a 350x looks like an almost direct bolt up!!
but i may be wrong i'm going off pics alone

Compare the wiring diagrams.
